I made all settings in tools->preferences->Prompt for debugger host for database debugging
and also removed antivirus and firewall.
delete existing sql developer and downloaded new one and tested
debug grands also given.
cleared the event log, temp file, unwanted registry.
but problem is not resolved.
Is your database on the same local network as your client machine, or are you connecting to a remote network (perhaps via VPN, or perhaps through a wireless router that is assigning a local IP address to your machine)?
